Project history: "Treasury" class cutters at all advantages had one significant lack: high (to Coast guard measures) cost. For this reason building of three last ships of this class have refused, re-ordered them under the new project of the smaller cutter. They have returned to single-shaft turbo-electrical machinery (as well as on "Lake" class), armament structure and requirements on speed having left without changes, in comparison with "Treasury".
Building of three cutters was originally planed, but in the summer of 1941 ten more were added which should replace "Lake" class ships, transferred to Royal Navy.
Low priority of program in days of war has led to that ordered in 1941 ships were launched only in 1944-1945. Possibility of the account of experience of operations became unique positive line of this long-term construction. Main guns became dual-purpose, AA armament was strengthened. Seaplanes have refused.
